WATER-BAG.

To all whom it may concern: 7

Be it known that I, DELIA A. CLIMEs, a citizen of the United States,residing at San Diego, county of San Diego, and State of California,have invented a new and useful Improvement in ater-Bags, of which thefollowing is a specification.

IVhile there is a need and a demand for a water bag which has an openingin the center or elsewhere which will permit of the water-bag beingplaced over a wound or sore without touching the wound or sore, yet suchwater-bags as are now constructed and on the marketv do not permit ofthe r being manufactured cheaply and economically, and sold at areasonable price, because of their bulky, awkward shape due to theirconcavo-convex form. c

It is the object of my invention to provide a simply-constructed waterbag with an opening which will permit of its opening being placed over awound or sore without touching the same and giving either cold or hotwater temperatures to the surrounding tissues, which bag can be madecheaply, packed compactly, sold at a low price and which when empty willoccupy much less space than if its form were permanently maintained byits outer wall being more extensive than an inner wall and having thesetwo walls meeting and joining-at their edges around the central opening.

In the accompanying drawing, forming a part hereof, Figure 1 is a sideelevation in:

part section showing the bag distended by water Fig. 2 is the same emptyand de.-..

fiated, Fig. 3 is a top plan and Fig. 4 is a detailed view of acollapsible tube in longitudinal section showing the flanges lying onthe walls.

' Walls 1 and 2 of my bag are parallel. or

flat and of the same size and may be of any desired shape. In the centerof each wall or elsewhere as may be desired, is an opening 3 of anydesired size of the same diameter in each wall. At this opening, wall 1is attached and fastened to the end of an elastic flexible collapsibletube 4, and wall 2 is fastened to the other end of said elastic flexiblecollapsible tube 4 of practically the same diameter as the opening ineach wall and thus the tube when made of circular shape forms an annularpartition around the opening in each wall and extends through the bagand the water therein contained from wall to wall and prevents the waterfrom escaping through the central opening, so as to permit such openingto be placed over a wound or sore.

This tube 4 may be round or'any other desired shape and fastened at eachend in any desired manner to the walls 1 and 2. The most desirablemethod of fastening said tube to the walls, as it now seems, is to makethe tube round with an annular shoulder or flange 7' formed in, onepiece with and attached to the outer circumference of the round'tube ateach end. This flange being flexible and of waterproof material may bedoubled over and passed through the openings in the walls .when the bagis being made so that the underneath surface of the flange at eachendwill lie down on the outside of each wall whereon it may be cementedor otherwise fastened into place so as to provide a watertight annularpartition around the central opening and extending through the bag fromwall to wall. This tube being also elastic and collapsible is ex-.tended when the bag is distended and collapsed when the bag is empty.The opening in the tube must coincide with the opening in the walls sothat the tube when fastened to each wall willcprovidea watertight openWhen the bag is distended with water this form of construction causes adepression to be formed about the central opening. The size of thedepression and the amount of the elevation surrounding it depends on themanner in which the seam is made,- that is the amount of the overlappingof the edges and the width of the seam at the outer edge of the bag.This depression enables the walls to remain in such a position as not totouch the wound or sore over which the central opening is placed and atthe same time the hollow of such depression tends to conserve the heatand equalize the temperature employed over the tissues to be treated. Atthe same time such depression is only effecinto the filling inlet 5,:thebag is more or less distended in proportion to the amount of waterpoured into the bag and wall 1 tends to separate and pull away from wall2 and the collapsible flexible and elastic.

tube 4, (to the ends of which walls 1 and 2 are fastened) permits suchwalls to separate from' each other for a distance governed by theamountof water poured into such bag, the length of the tube 4 connecting thetwo walls and the limit of the stretch in the rubber or other materialcomposing said tube acting as an elastic annular partition, while thewater is held in the bag by the usual screw stopper 6.

\Vhen the bag is empty of water, it is evident that the walls willcollapse, come together and lie on each other and the central annularpartition will also collapse thus permitting the bag to occupy lessspace and be packed in a flat box and also permit of the bag being madein the ordinary way ;and thus sold to the user at a very much lowerprice than those now 011 the market and thus allow it to be placedwithin the .reach of many more persons needing it than is the casetoday.

Such a bag can be not only used for hot water, cold water or ice'andapplied to any portion of the body where wounds, sores, boils,inflammations, or lesions of the tis sues exist, so as to apply heat orcold to the surrounding tissues without any weight.

coming on the wound, sore, etc. but on account of the greaterdistensibility can be I used with comfort in place of the usualaircushions for invalids and for many other purposes not necessary hereto specify.

I am aware that water bags having a central opening have been heretoforemade fitIldllkGWlSG those which are of a permanent concavo-convex formdue to their be- .ing made of the segments of spheres or with an outerwall more extensive than an inner wall and hence do not claim thesefeatures but do expressly hereby disavow and disclaim any intention toclaim these tom walls, and a collapsible tube secured to said walls andextending through the body of the bag from one-of said apertures to theother, said walls being so formed that theywill be dished about each endof the tube when the walls'are distended.

2. A water bag comprising a body, including top and bottom walls offlexible water-proof material united at their margins and each having anaperture formed therein, each of said walls including a lapseam producedby cutting the wall. from the aperture therein to the margin and lappingone edgeover the other to a greater degree adjacent the margin thanadjacent said aperture, and a collapsible tube secured to said walls andextending through the body of the bag. from one of said apertures to theother..

3. A water bag comprising a body formed by top and bottom walls offlexible water-proof material united at their mar-i gins ancleach havingan aperture therein, and an elastic collapsible tube extending throughsaid bodyand having its ends secured to the top and bottom walls aboutthe apertures therein, saidtube acting to draw said walls toward eachother when distended and permitting them to come together throughouttheir area when the bag is not distended.
